Solved Basic Comparison Test 4 ï Marks Use The Basic Chegg In this section we will discuss using the comparison test and limit comparison tests to determine if an infinite series converges or diverges. in order to use either test the terms of the infinite series must be positive. proofs for both tests are also given. In this section, we show how to use comparison tests to determine the convergence or divergence of a series by comparing it to a series whose convergence or divergence is known.
Solved We Want To Use The Basic Comparison Test Sometimes Chegg When you compare 2 series, there are 4 possibil ities: if the bigger series converges, so does the smaller series and, if the smaller series diverges, so does the bigger series. the other 2 possibilities are not so conclusive: if the smaller series converges, or if the bigger series diverges, we get absolutely no information about the other series. We will use the limit comparison test (coming up) to test this series. The limit comparison test allows us to “ignore” some parts of the terms of a series that cause algebraic dificulties when using the bct, but which have no effect on the convergence of the series. Like the integral test, the so called comparison test can be used to show both convergence and divergence. in the case of the integral test, a single calculation will confirm whichever is the case.

In applying the comparison test, it's essential to identify an appropriate series for comparison. often, this involves selecting a series with terms that, for large 'n', approximate those of your target series but which are simpler and well understood in terms of convergence. Since \ (\sum {n=1}^\infty b n=\sum {n=1}^\infty\frac1 {n^2}\) is a p series with \ (p=2>1\), it converges, and therefore, the series \ (\sum {n=1}^\infty\frac1 {4n^2 1}\) converges by the limit comparison test. The idea of the basic comparison test is to learn something about a series by comparing it to another series, about which we know whether it converges or diverges.
